Airport HistoryEst. 1995
Denver International Airport opened on 28 February 1995, sixteen months later than planned, replacing the aging Stapleton International Airport whose closely spaced runways caused chronic weather delays. Built on more than 33,000 acres northeast of downtown Denver — enough land that several other major U.S. airports could fit inside its perimeter — the project's cost rose from an original $3.7 billion budget to roughly $4.8 billion, driven largely by a fully automated baggage-handling system that famously shredded luggage during pre-opening tests and was ultimately abandoned in 2005. Despite its rocky start, DEN grew into one of the busiest airports in the world and United Airlines' largest hub, setting a new all-time passenger record in 2025. Its distinctive peaked-roof terminal and eclectic public art have also made it the subject of numerous internet conspiracy theories, which the airport has never taken seriously and has since leaned into with a self-aware 'Conspiracy Theories Uncovered' exhibit — a point worth noting explicitly, since the theories themselves (secret bunkers, Freemason or occult symbolism, and so on) are unfounded urban legend, not documented history.
Ground broke in September 1989 on a new airport northeast of Denver intended to replace the capacity-constrained Stapleton International Airport.
A May 1994 press preview of the airport's showcase automated baggage-handling system revealed it was shredding and misdirecting luggage, forcing officials to postpone the planned opening.
DEN opened on 28 February 1995, replacing Stapleton International Airport, which closed the same day.
After years of partial use and repeated malfunctions, the original automated baggage system was shut down for good in September 2005 in favor of conventional manual handling.
DEN launched a large public-private partnership to renovate its Jeppesen Terminal 'Great Hall,' intended to modernize security and passenger flow.
The airport terminated its roughly $1.8 billion Great Hall renovation contract in 2019 after disputes over structural concerns and project management, restarting the renovation under new arrangements.
DEN handled a record 82.4 million passengers in 2025, reinforcing its position as one of the three busiest airports in the United States.
Editorial content based on public airport records and contemporary news coverage. Note: the recurring conspiracy theories about DEN (secret tunnels, Freemason or occult symbolism, etc.) are widely circulated online but are unfounded urban legend, not established history, and are included here only to note their existence and debunk them. 2025 passenger-record figures are recent and may be revised.
